Title: Picture information processor
Inventor: SUGINO TAKASHI
IPC: G06T5/00
Filed: 1985-12-25
Abstract: PURPOSE:To obtain a picture with high quality applying binarization expression emphasizing the gradation for a photographic picture and applying binarization expression emphasizing the resolution for a character picture. CONSTITUTION:When a character flag signal read from a picture memory 4 is at '0', a data identification means identifies a data as a color gradation picture data. Thus, a data selector 8 selects a density modulation data applying density modulation to a color gradation picture data and outputs the result to a display device or a printer. Thus, the photographic picture with high gradation is obtained. Further, a data identification means identifies a data as a character pattern data when a character flag signal read from the picture memory 4 is at '1'. Thus, the data selector 8 selects the character pattern data and gives output to the display device or the printer. Thus, the character picture with high resolution is obtained on the same screen or on the same paper as the photographic picture.

Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To lessen the change in the coating weight of chromium and the change in appearance in spite of a change in a line speed by controlling the pressure for blowing a chemical conversion treating liquid according to the line speed. SOLUTION: The treating liquid 14 is blown by sprayers 5 to 9 to a galvanized steel sheet 10 to form chromate treating films. A pulse generator 27 sends the signal meeting the number of revolutions of a bridle roll 28 to a controller 29. This controller 29 calculates the line speed and controls pressure control valves 17a to d in accordance with this speed, thereby controlling the pressure of the treating liquid. The pressure is increased when the line speed is high and the pressure is lowered when the line pressure is low. The controller 29 controls the supply rate of the treating liquid by opening and closing stop valves 18 to 21. The treating liquid is squeezed from the galvanized steel sheet by wringer rolls 3, 4 and the steel sheet is dried.  The outer sides at both edges of the metallic sheet 10 are extended and provided with shielding members to prevent the infiltrating of the treating liquid to the opposite surface of the metallic sheet 10. Since there are no use and stop of nozzles, nozzle clogging does not arise.

Abstract: PURPOSE:To efficiently remove poisonous substances remaining in a reaction container after a dry etching is performed and to improve an etching accuracy by a method wherein, after the dry etching is performed on substrates, oxygen gas flows into the reaction container and ozone and a nascent oxygen which are generated by ultraviolet ray irradiation are used. CONSTITUTION:A dry etching device 1 has a high-purity quartz window 6 and a low- pressure mercury-arc lamp 5 for ultraviolet ray emission,an anode 7 is designed in a movable type and can be bilaterally shifted, and a susceptor 10 can be directly irradiated with ultraviolet light. After an etching is performed, O2 gas flows into a reaction container 2 until the gas pressure in the interior reaches a normal pressure. Thereafter, irradiation of ultraviolet light of about 10% of light of 2,537Angstrom  wavelength from the low-pressure mercury-arc lamp 5 takes place in the reaction container 2 through the high-purity quartz window 6. As the result, ozone (O3) and nascent oxygen (O*) having strong oxidative effect are produced. Residues are subjected to oxidative destruction by the strong oxidative effect of the O* and O3, and CO2 and Cl2 are produced and exhausted through 9. Moreover, photo resists are also decomposed and removed by the O* and O3. Thus, the interior of the reaction container is cleaned by a 'UV-ozone treatment'.
